I don't understand why "4. Stay at your company and try to change culture within by organizing collectively, either through the guise of a union or informally" isn't also something you are free to do, besides that you think doing so is not "do[ing] something positive to the society", but is instead "becoming a bunch of cry babies."

Also why is 3 binary? If I am a minority investor in a company, I am not free to criticize the management? I have to buy the majority of the company and fire the management?

It kind of seems like you don't actually understand that soft power exists. The canonical book on this within organizational politics is "Exit, Voice and Loyalty". Have you ever had a social interaction in your entire life? Not everything is an ultimatum, some things are conversations.
